To all whom it may concern: I Be it lmown' that I, GEorL @.-*Grmnw1oxr,

a citizen of: the U nite'd States, and. resident of llewton, ='c'oun-ty--of- Middlesexffitate of llliassachusetts, have invented an improve ment in: Bubbler Fountains, of which the following description, in connection wit-lithe accompanying 'drawing,' a specification,

like parts.

like 'char'actersonthe drawing representing This invention relates to bubbler "-if'oun-l tains. and has for its object to providelgan improved b ubbler which is simple in its con struction and inexpensive to manua'cture,-

which is provided with a perfectly smooth; exterior surface so that it can be easily-kept clean, which constructed. so that it can be readily adjusted for different pressures, and

which has other features of improvement,

all as will be more fully hereinafter setforth;

In order to give i an understanding'i of my invention, I hawe 'illustrated in the drawings a selected embodimentthereo't which will.

' now lJB-ClESCIllDGd, after-whichthe-novel features will be pointedout; in -ithe l appended claims.

Fig. 1 is a side view of a bubbler embodying my invention:

Fig. 2 is a vertical sectional View; Fig. 3 is a bottom plan view; I Fig. 4 is a section on the line 44, Fig. 2. My improved bubbler comprises a head portion 1 and a neck portion 2, the latter being constructed to be screw-threaded to a pipe in usual manner. The head portion 1 is provided with the interior chamber 3 and with the discharge port 4:. The neck2 is hollow and is interiorly screw-threaded.

Situated within the neck 2 are two plugs 5 and 6 each of which preferably has screwthreaded engagement with the neck. The plug 5 is provided with a central duct 7 and the plug 6 is provided with a plurality of ducts 8 which are out of line with the duct 7. This plug 6 is also provided with a screwdriver slot 9 in its upper face, and the dis charge opening 4 is of suflicient size to permit a screw-driver to be inserted therethrough for the purpose of adjusting the plug 6. The purpose of these plugs is to regulate the flow of water through the bubbler according to the pressure in the water system to which the bubbler is attached.

The two plugs will be adjusted so as to leave a. space between them, the extent of this space :depending upon thepressur of the water. nlfnthe .water. pressureflis-nhigh the plug afi will be.screwe'd.'down.,closer to-th'e;

plug 5. than. if the water. pressures iis relatively: low. The space. ibetween thedplugspfii and 6 .constitutesae pressure-regulatingspace which regulates the pressure at which the water is .i delivere'dthrough a :the: ducts 8 .and thus regulates the s height to. which the :water Willi rise: asz' it issues from .-rtl1e. discharge single F du'ct 75111. the: plug-:5. The tota1 cross= opening 4. i It- .will' be .noted? that thererare; a plurality of ducts 8. i n' the p'lugi Grand a sectional area of the ducts 8 'isgreaterthanr that of the duct 7. and, therefore, the water has. aofreer .'tlow '=fi-om the rchamber .between theiplugs than it has into theichamber. The

result'ofithe freer discharge from l'this.:chamber is that the pressure in the chambenwj'l'la be. appreciably reducedlbelow that iin th'e an- .sure into the space between the ducts and will then flow through the ducts 8 into the chamber 3. The velocity with which it flows 75. let pipe, and this pressure-isstill furtheriree duced in the chamber 3becausezthe: discharge opening lxhas a greater cross-sectional [area than :the discharge from 'the chamber'be-x into the chamber 3 will depend something on the relative adjustment of the plugs 5 and 6, and it is the intention that these should be so adjusted that when the chamber 8 is filled, the pressure will force the water out through the discharge opening 4 in a stream which will rise a short distance above the top of the head. Owingto the presence of the flange 10 which makes an elongated dis.- charge opening 4, the stream which is delivered from the bubbler will always assume a certain direction, thus making it easier to drink from the bubbler.

The'plug 6 can be, readily adjusted; from v l the exterior of the head and thereforethe bubbler can be adjusted for any pressure while it is attached to the system, and by simply inserting a screw-driver through the opening 4 and turning the plug 6 in one direction or the other.

It sometimes happens that mischievous persons will insert a pencil or other obstruction into the discharge-opening of the bubbler for the purpose of increasing the pressure in the chamber 8, thus causing a small stream of water to be thrown from the bubbler a considerable distance. In order to avoid anything of this sort, I propose to make the waste openings 11 of suflicient cross sectional area so that if the discharge opening 4 is closed orxpartially closed, the waterin the chamber 3 can flow out of the waste openings at a sufiiciently rapid rate to prevent an undue pressure from building up in the chamber 3. These waste openings or vent ports, however, are not sufficiently large to interfere with the ordinary use of the bubbler when the discharge 4 is unobstructed.

-The plug 6 not only constitutes a regulating plug, but it also constitutes a valve, for by. screwing said plug hard down against the plug 5 the water will be completely shut off.

It will be noted that the exterior surface of-the head 1 is perfectly smooth and free from indentations, recesses or grooves. This is a decided advantage because it facilitates the cleaning of the bubbler and dispenses with any hollows or recesses in which dirt or filth may collect.

I claim:

1. A bubbler having a chambered head and a hollow neck portion, said head having a discharge opening, two plugs screwthreaded into the neck portion and adjustable relative to each other, both plugs having apertures therethrough out of alignwith a central duct, a regulating plug.

screw-threaded into the neck above the firstnamed plug and spaced therefrom, said regulating plug being provided with a plurality of ducts out of line with the central duct and having a total ,cross sectional area greater than that of the central duct.

3. A bubbler comprising ahead portion and neck portion, said head portion having a smooth exterior surface free from indentations, and also having an exterior chamber and a discharge opening, said neck portion being hollow, and two plugs screwthreaded into the neck portion but spaced from each other, both plugs having ducts therethrough, the ducts through the outer plug having a total cross-sectional area greater than those through the inner plug.

In testimony whereof, I have signed my name to this specification.
